Reservoir and Completions Engineer

Daniela Arias Ortiz works with ResFrac as a reservoir and completions engineer at ResFrac, focusing on reservoir data analysis, improving workflows, and customer support.

She earned her bachelor’s degree in petroleum engineering from the National University of Colombia in 2017. Her curiosity for unconventional reservoirs took her to Saudi Arabia in 2018, where she pursued her Master’s and PhD at KAUST University. There, she dove deep into understanding flow behavior in hydraulically fractured shale wells, the impact of hydraulic fracture geometry on well productivity, and forecasting field production from shale reservoirs.

When she’s not solving reservoir puzzles, Daniela enjoys live music, trying new foods, and staying active. You can often find her climbing, hiking, doing CrossFit, or practicing aerial silks. Although she doesn’t dive, Daniela enjoys snorkeling and exploring the underwater world. She’s also a coffee enthusiast who loves traveling, especially when it involves exploring new cultures!

The influence of well configuration on water loss in Enhanced Geothermal Systems

Recently, ‘water loss’ has been a hot topic of discussion for EGS. Fervo reported that they have been producing only 70% of the fluid volumes that they have been injecting at their Project Red. The FORGE project reported a roughly 10% water loss rate. Because projects will have finite water rights, these results have led to concern that growth of EGS will be limited by excessive water consumption. This is a valid concern, and water availability is a legitimate factor in site-selection and project engineering. However, I believe that the problem has been overstated.

2026 ResFrac Annual Symposium Recap

On June 25, 2026, we got the ResFrac community together both in-person at the ExxonMobil campus in Spring, Texas, and virtually around the globe for our Annual Symposium. With our community growing as fast as it is, the energy in the room was absolutely buzzing. We had a jam-packed day of operator case studies, deep-dive technical sessions, and some incredible geomechanical insights from industry legends.

FracTest – An Online Tool for DFIT Interpretation

This week, we are releasing FracTest, a web-based application for interpretation of diagnostic fracture injection tests (DFITs). FracTest is available at resapps.resfrac.com, alongside our other two ResApps, StageOpt and IntTest. DFITs are small-volume fracture injection tests used to estimate stress, pore pressure, and permeability. These quantities form the foundation of the fracture and reservoir engineering work that we do in ResFrac, and so we view DFIT interpretation as one of the most important parts of our workflow.
